IMPROVEMENTSIN HEEL-STIFFENERS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. l 80,340, dated July 25, 1876; application filed January 29, 1876.

To all whom it may concern.' y

Be it known that I, JAMES L. HATCH, of Rochester, in the county of Monroe and State of NewYork, have invented Improvements in Blanks for Heel-Stiffeners, Toe-Caps, and Box-Toes, of which the following is a specification:

This invention relates to blanks of leather, or leather-board, or leather and leather-board, for the manufacture of heel-stiffeners, toecaps,or box-toes, is an improvement on United States Patents Nos. 129,338 and 146,252, and.

of ordinary construction; Fig. 2, a blank for a h eel-stiiiener, with its edge corrugated; Fig. 3, an under side View of the blank Fig. 2, showing its crimped or gathered flange. Fig. 4 represents a. blank for a toe-cap, or box-toe; and Fig. 5 the blank crimped or molded to l toe-form.

The stiener-blank A is formed preferably of leather and leather-board united by'a water-proof or india-rubber cement, as described in a patent heretofore granted to me, but one or two pieces of leather or leatherboard, or leather and leather-board, or othermaterial commonly used for stiffeners or toecaps, may be used instead.

The lower edges of these blanks (see Figs. 2

and 4) areicorrugated, as shown at a, by passing their flange-forming edges between, preferably, a pair of toothed rollers, or a toothed and plain roller, a gage being used, if desired, to guide the edges of the blanks, and determine the length of' the corrugations.

The corrugations form in the flange alternate elevations b and 'depressions c, and when the corrugated edge is bent over to form the llange--any well-known crimping or flangeturning devices being employed-the elevated portions b approach and abut, while the depressed portions c have a tendency to move in an opposite direction, forming a substantially even and uniformly crimpedor gathered ange. A smooth and evenly-formed ange saves much time in the process of lasting.'

The corrugations made along the edge of the blank permit the gathers to be formed closer and more compactly than were the corrugations omitted, and the flange may therefore he turned into a smaller curve than heretofore, and when formed will bebetter retained in position. y

II claiml. A blank for the manufacture of' heel- JAMES L. HATCH.
